Read the two statements and choose the correct option.

I. $\hat{i} + \hat{j}$ and $-\hat{i} - \hat{j}$ are collinear vectors.

II. Two equal vectors must have the same initial point.

Explanation

1. 01

   I: $-\hat{i} - \hat{j} = -1(\hat{i} + \hat{j})$, a scalar multiple, so they are collinear. True.

2. 02

   II: equal vectors need only the same magnitude and the same direction; their initial points can differ. False.
